Few new type of marine structures suitable for innovative development of construction industries

Ocean wave damping is one of the essential activity required for coastal erosion protection, open sea construction, marine aquaculture development and for reducing wave loads on marine structures. Many different structures are used around the world such as offshore rubble mound breakwater, floating breakwaters, caisson type of offshore vertical walls etc. In the present study, an attempt is made on three different types of wave dampers for different purposes of applications. One is on new type of floating breakwater; another one is wave dampers with series of perforated vertical wall with impervious wall at the rear end; he last one is perforated slotted vertical barriers. Studies on hydrodynamic performances such as wave transmissions, wave forces etc. were carried out and the innovation fetched three different US patents. This paper discusses in brief the scientific details of these new wave dampers. The knowledge is expected to be used by any coastal countries depends on their needs and economic possibilities.
